I too say yes, it can get worse. I will also say that with the right meds, therapy, and willingness to stay the course until stability is found it actually can and does get better.

Then it gets worse and better and as the title says: Bi polar. Up and down. But I know for me once I get stable I tend to stay that way for a while. The challenge is hanging in there while the docs help me find the right meds.

Best wishes and lots of hopeful hugs.
